I bought a very nice playing upper level saxophone. It's says Mercury Design in USA. The seller told me the parts came from Korea and it was assembled in usa.
Seller said: Double arms on all claps in the low registeres just like the yanagisawa's. Inscription: "Mercury musical design USA" Serial nummer JF0117H8.
It plays incredible, but I can't find any information about this peculiar sax. And the hammer blow is really rare. Have you seem hammer blow (does it translate like this: hamerslag) saxes before? Does anybody have any information about this sax?
I only found this strange website http://www.lk-js.com/en/info.asp?id=4
